Wordpress removes title attribute from images

[ukdmbfan]

For everyone apart from super-admin users, WordPress will remove a title attribute defined in an <img> tag. This is because it's not defined in the /wp-includes/kses.php file as being a valid attribute for <img>.

It may be that WordPress doesn't consider title to be a valid attribute (even though it's a standard W3C HTML attribute) which is fine, but WordPress also provides an input box for the title in the image editing popup, which adds the title attribute to the <img> tag, which then doesn't save for anyone other than a super-admin user (even though all users can save a value in that box).

Patch adds title to allowed img attributes.

However, the title attribute is allowed anywhere in HTML. Is there any reason why we can't tell kses to allow it on all elements? I can't see any security reason not to let authors use title attributes wherever they like. Something like 16713.2​ maybe.

We should fix many standard tags in one go, see #20210.
